It's impossible to say for sure what's a vanity address and what's generated purely at random, but 1CFBdvaiZgZPTZERqnezAtDQJuGHKoHSzg is 34 characters with no digits in it other than the initial '1'. That may well be a vanity address. Then again on average 1 in every 515 34-character addresses you generate won't have any digits in them other than the leading 1, so possibly not.

Yessir! I got a little crazy with vanitygen and succeeded. It
should've taken about 70 days of computation time but I got lucky and
found it in about a week... (notice no digits either, only uppercase
letters).

Unfortunately, it's so cool that people don't even recognize it as a
Bitcoin address :)

I personally generated this address: 1BoyishnessfwHq3wSkCkJ7iafUdjhghfU which is the longest one I'm aware of that's not mixed case. It was generated by feeding oclvanitygen a large number of potential prefixes from a large wordlist.

OK, so right now time to raise some money and open a VC fund investing in regenerative communities - independent food, energy, water production and focus on education and new post-scarcity paradigm economy.

EDIT / UPDATE: Out of curiosity tried running the command as if I was to bruteforce it with the exact capitalisation:

"Then again on average 1 in every 515 34-character addresses you generate won't have any digits in them other than the leading 1"

I think it's 1 in every 261 34 char BTC addresses. It's because there are only 9 numbers available (0 not base 58 conform):
(58/49)³³ = 261.007...

One can create easily long vanity addresses like someone did with this one:
1FuckYouFuckYouFuckYouFuckYouz76RT
However, the creator cannot create the priv key so money send to those addresses aren't spendable.
